In addition, we will examine some of the theory behind the science that causes most scientists to be concerned.Included below are links to the original data/studies that will allow you to verify that the information on this page is accurate.In East Africa at the same time the small lakes in the Kenya rift valley rose to combine or to create riverain links over the normal watersheds, while to their north Lake Rudolf reached a height sufficient to help feed the White Nile system.Age estimates for ancient lakes are important for determining their histories and their rates off biotic and tectonic evolution.Age estimates from the RSRM suggest that the structural basins of central Lake Tanganyika began to form between 9 and 12 Ma.

Evaluating the sum of these processes and reconstructing them from sediment records of lake history requires a range of methods and a multi-proxy approach.

The RSRM age estimates for Lake Tanganyika are considerably younger than most prior estimates and clarify the extensional history of the western branch of the East African Rift system.

New sediment core data from a unique slow-sedimentation rate site in Lake Tanganyika contain a much longer and continuous record of limnological response to climate change than have been previously observed in equatorial regions of central Africa.

Following this interval there is a shift to higher values of δC, indicating a possible shift to C-4 pathway-dominated grassland-type vegetation in the catchment, and indicating cooler, dryer conditions from ∼ 55 k yr through the LGM.

Two seismic sequence boundaries are observed at shallow stratigraphic levels in the seismic reflection data, and the upper boundary correlates to a major discontinuity near the base of T97-52V.

We interpret these discontinuities to reflect major, prolonged drops in lake level below the core site (393 m), with the lower boundary correlating to marine oxygen isotope Stage 6.
